IGMP Snooping is a network switch feature that listens to Internet Group Management Protocol (IGMP) traffic to optimize the distribution of multicast streams. Without IGMP Snooping, multicast streams are indiscriminately sent to all ports, which can cause network congestion and waste bandwidth. For instance: Without IGMP…
Yes, you can set a specific port for IGMP query on a Zyxel web-managed switch. This is done in the IGMP settings by selecting a port from the 'IGMP Static Router Port' dropdown menu. Alternatively, you can select 'Auto' to allow any port to be used as an IGMP query port after receiving an IGMP query.
On a web-managed switch, the "Unknown Multicast Drop" feature within IGMP Snooping ensures that multicast traffic is only sent to ports with devices requesting to join a specific multicast group. If a multicast frame doesn't correspond to any group listed in the switch's IGMP table — essentially an 'unknown' group — this…
Scenario: Imagine a network like a set of mailboxes at an apartment complex. Without IGMP Snooping, the mail carrier puts a copy of a specific flyer into every single mailbox, whether the resident is interested or not. This means some people get mail they don't want, which is a waste of paper. With IGMP Snooping enabled on…
The behavior of IGMP Unknown Multicast Frame is an independent feature. It functions without the need to enable the IGMP-snooping feature. This feature is designed to manage the handling of multicast frames for which the switch does not have any IGMP snooping information. It helps in controlling and optimizing multicast…
This guide aims to demonstrate how to prioritize multicast streams using the Quality of Service (QoS) settings on the GS1900 Series switches. Steps to Assign Higher Priority to Multicast Streams: Configure CoS Value: Navigate to Configuration > QoS > General. Select the specific port connected to the stream server. Assign…
Dante controller uses mDNS to discover the Dante devices. Since mDNS cannot be routed to different subnets, please make sure the Dante controller and the Dante devices are in the same subnet.
This problem could be because some of the Dante device’s clock is inconsistent with the clock leader. Please make sure the static multicast forwarding group for the PTP protocol has been set. For static multicast forwarding group configuration, please reference: Configuring Zyxel Switch for the DANTE Network — Zyxel…
Introduction DANTE Network is an Audio over Ethernet system developed by Audinate Corporation. It uses multicast to stream audio in the IP network. This topic will guide users to configure their switches for the DANTE network. Topology Configuration Use Networked AV wizard to set up IGMP snooping. Choose Networked AV Mode…
The example shows administrators how to configure IGMP Snooping for multicast clients and steaming servers in the same VLAN. When MediaServer multicasts the stream, IGMP snooping allows the switch to learn multicast groups without having the user to manually configure the each switch. This prevents the switch from flooding…
The example shows administrators how to configure IGMP routing on the Zyxel Layer 3 switch. This is necessary when the multicast clients are in a different LAN or VLAN from the streaming server. Note: All network IP addresses and subnet masks are used as examples in this article. Please replace them with your actual…
Before we begin designing an IPTV Network, there are 3 important concepts of Zyxel’s IGMP (Internet Group Management Protocol) and IGMP Snooping that administrators should be aware of. 1. What are General Queries and Group Specific Queries? General Query: The querier will send query messages to the multicast clients to…
A common misconfiguration occurs when the port of an uplink switch has been configured to "Immediate Leave". Keep in mind that "Immediate Leave" is a setting designed for ports that are directly connected to your IPTV's set-top box. In a common IPTV solution where all ports are set to "normal leave", the IPTV's set-top box…
